Specification of Letters Patent.

. Patented. April 6, 1909.

' Application filed August 20, 1988; Serial No. 449,397.

T 0 all whom it may concern: Be it known that l, LAURENCE S. Lann- MAN,a citizen of the United States, and

wherein the longitudinal line-wires or strand wires are united atintervals to transverse 1 wires forming stays, by means of pieces ofmetal which are electrically welded to thewires about theirintersection.

vide a fence having greater strength and durabilitythan the ordinarywire fence, the wires of which are welded at their intersection'. r

The objects of the invention arealso to provide a form of constructionwhich permits of the fence being made in a great variety of shapes bothfor ornamentation and strength at a very low cost.

Referring to the drawings: Figurel' is a rear elevation of a portion ofa fence con- Y Fig.2,

structed according to my invention. is a plan view of one of the weldpieces. Fig. '3 is a cross section of Fig. 2. Fig. 4 is a plan View ofany alternate form of weld piece. Fig. 5 is a cross section of Fig. i. 6is a plan iew of an alternate form of weld piece. Fig. 7 is a crosssection of Fig. 6. Fig. 8 is an end View partly. in cross section andwith parts broken away of Fig. 1'; Fig. 9 is a detail perspective, viewshowing the intersection of the wires Fig. 10 is a detail of analternate construction.

In the drawings, A designates the strand wires of the fence and Bdesignates the stay wires which are arranged to cross the strand wiresat any desired angle, the wires being securely held together at theirintersections by means of buttons or small pieces of sheet metal C,-which in the present instance are provided with at least one ridgeD'which projects' above the surface of the adjacent metal of the buttonand corresponds approximately in cross-sectional area to that of thewires, so that when an electric welding current is passed through theridge D and the wires A and B and the same are forced together, in anydesired manner, the metal at the points of contact both on the wires andthe ridge D will be heated to-the welding temperature after which thesame are forced together until the metal ofthe-button C and the portionof the wires adjacent to the points of welded union meet and contact soas to short-circuit the welding current by affording a larger )ath forits assage, the metal of the wires eing welde to ridge Dat-eachintersection i of the wires as shown in vFi 8. The buttons C areusuaFly constructed of sheet metal suitably ressed to form the ridge Dalthough the ri ge D may be madein any other desiredy namier, it beingimmaterial whether the ridge D is forced up out of x the metal as' shownin Figs; 5 and 7 or whether The objects of the invention are to pro-jthe same is simply pressed as shown in Figs. 2, 3,4 and 5. l

If desired the buttons may be provided with a plurality of concentricridges, pro vided the buttons are made large enough to space thedifferent ridges far enough apart so as to facilitate the weldingcurrent being short circuited when the button is pressed in contact withthe wirefij-and also to facilitate the ridges being brought to theproper welding temperature. V

it is obvious that the buttons may be made any desired shape so as toharmonize with the general design ofthe fence and it is also obviousthat theridges are not necessarily made continuous and can ust as wellbe pro .vided only where the wires are to be=welded thereto, theremaining portions of the ridges being of no advantage in welding theparts together but of considerable advantage as the same is easier toput in place and manufacture.

The buttons 0. also'permit' wiresE beingwelded to the same, so as toin-' crease the strength of the fence and change the design in a greatvariety of ways such as that shown in Fig. 10.

-As shown in Fig; 1 the cross stay wires E are made in short lengths butthe same may cheaper. to

be made in one piece so as to reach from the top strand to thebottoinstrand wire-of the fence. 4

When the wires are made to cross each other such as the wires A and B,the same are preferably bent or kinked at their intersection as shown inFig. 8 so as to give a more finished appearance to the fence andlambtate the ridge D connng in contact with the wires where it crossesthem.

The button C as before described, permits of the wires A and B beingwelded at of the crossfour different laces at each intersection therebyobvietingell chances of the wires ever coining-apart. The button alsohas the additional advantage of permitting cross wires'to be welded tothe same so as "to in- 'ereasethe strength utility and beauty of themade and still fall within the scope of the appended claims.

What I claim 1s: v 1, A ire fence comprising a series of strand wiiesand a series of stay Wires, nude ridged butt0n, said strand and stayWires being weld-united to the. ridges of said button.

2. A Wire .fence comprising a series of strand wires and 11 series ofsta, wires, 2. ridged button, the ridges of said utton beingapproximately of the same cross-sectional area as the strend'a-nd stayWires tofwhich the ridges of said button are Weld-united at theintersection of said strand and stay wires.

In testimony whereof I have signed this.
